SOCIAL RELATIONSHIPS BETWEEN MALES AND FEMALES IN ROCK LIZARD (DAREVSKIA BRAUNERI, LACERTIDAE). 1. FRIENDLY MONOGYNY IN MALES AND POLYANDRY IN FEMALES

摘要

A natural settlement of rock lizard was observed on the Navagir Ridge (Krasnodar Territory) in 1997-2006. In different years, the settlement included from 18 to 28 adult individuals. The frequency of affiliative behavior in the course of intersexual contacts and the frequency of attendance of comfort female areas by male allowed us to reveal three types of intersexual dyad relationships. They are as follows: (1) the friendly, or A-interrelations (maximal values of both indices; Maximal duration of interrelation; and the only reason for the termination of interrelations death of one of the partners); (2) the R-interrelations (minimal values of all the indices and the main reason for the termination of interrelations female resettlement); and (3) the N interrelations (intermediate values of indices and the main reason for the termination of interrelations transition to another type of interrelation). Both males and females could simultaneously have several R-and N-interrelations. In males, the A-attitude towards only single female was always observed. In females, the A-attitude may be formed simultaneously towards two males. Approximately one third of the friendly connected groups were polyandrous triads (female and two males), the rest were monogamous (male and female). Apparently, in this species there is a general tendency towards social polyandry, which is restrained by certain social and/or environmental factors.
